. The glacier flows at a rate of per day, resulting in around 20 billion tonnes of
icebergs calved off and passing out of the fjord every year.
Icebergs breaking from the glacier are often so large —up to a kilometer (3,300 ft) in height— that they are too tall to float down the fjord and lie stuck on the bottom of its shallower areas, sometimes for years, until they are broken up by the force of the glacier and icebergs further up the fjord. On breaking up, the icebergs emerge into the open sea and initially travel north with ocean currents before turning south and running into the
